HMD Display Adjustment for Smartphone Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display systems for mobile terminal devices, such as smartphones, face difficulties in ensuring that images displayed on the device are easily viewable when they overlap with the external scene viewed through a Head-Mounted Display (HMD), leading to visibility issues.
Innovation Solution
A display system comprising a HMD and an information processor that includes a first display unit for visually recognizing the external scene, a position input unit for receiving input operations, and adjustment mechanisms to determine and adjust the display of the image on the HMD based on the position and orientation of the information processor relative to the HMD, ensuring that the information processor's display is not obscured by the HMD's image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the image displayed on the HMD and the image displayed on the smartphone overlap, then the HMD can display content, but the image displayed on the smartphone becomes difficult to view
Solution Approach 1:
The patent applies local quality by adjusting the transparency or visibility of the HMD display in specific regions where the smartphone screen is detected. The display control unit modifies the local properties of the HMD image based on the position of the smartphone, making certain areas more transparent to improve smartphone visibility while maintaining content display functionality.
Solution Approach 2:
The patent implements dynamics by continuously adjusting the HMD display characteristics based on the real-time position of the smartphone. The system dynamically changes the display parameters of the HMD image according to the detected smartphone location, enabling adaptive optimization of visibility as the smartphone moves.
2Loss of information
If the HMD displays an image overlapping the external scene, then information can be provided to the user, but the image on the information processor becomes difficult to view
Solution Approach 1:
The patent applies local quality by selectively adjusting the HMD display properties in the region where the information processor screen is located. The display control unit modifies only the local area corresponding to the processor screen position, maintaining overall information delivery while improving local visibility for operation.
Solution Approach 2:
The patent implements feedback by using the position detection unit to continuously monitor the information processor's location and adjusting the HMD display accordingly. The system receives feedback about screen position and dynamically optimizes the overlay to maintain both information delivery and operational ease.
3Illumination intensity
If the position of the second display unit is detected to adjust the first image display, then visibility is improved, but the system complexity increases
Solution Approach 1:
The patent applies universality by integrating multiple functions into the existing HMD components. The display control unit that already manages HMD image display is extended to also handle the optimization based on processor position, eliminating the need for separate control systems and reducing overall complexity.
Solution Approach 2:
The patent merges the position detection functionality with the existing display control system. By combining these functions into an integrated control unit, the patent reduces system complexity while achieving improved visibility through coordinated control of image display based on detected positions.
